Who, when you take a working pressure at the meter in a property with multi appliances (or boiler and cooker) record the measurement on a cp12 with all the appliances working?
Or do you just have the appliance with the largest load on?
As an example scenario:
Property has a combi boiler and cooker
Working pressure at METER with boiler in service mode and 3 rings on cooker 18.5mb ( below 19mb)
Working pressure at METER boiler only (service mode) 19mb (within tolerance).
Working pressure at BOILER within 1mb tolerance so no issue with pipe sizing.
Would you call this into the grid to increase pressure at regulator?
I know engineers who only have the boiler on when doing working pressure at the meter so in the above scenario would pass this and walk away.
